Well, only about a week before I bought the World Kit for Poser, I had purchased Animatek's World Builder, and I already have Bryce. I was looking for a quick way to create environments and the World Kit is just that. Poser has me spoiled with the ability to set up a scene and get final renders within minutes. Animatek's World Builder is REALLY powerful, but also EXTREMELY cumbersome and frustrating. Don't bother with it unless you have LOTS of time to wait for even the simple things, and can deal with constant crashes. Yes you can import Poser figures directly into World Builder, but you still have to wait for every single blade of grass to be rendered individually. Cool, but time consuming. If Harv comes out with a few trees and plants, there are already building construction kits available, I think I can pack Bryce away for a long time until I need some kind of "show-piece" which justifies it. I think this is a great idea because it is scaled perfectly to poser, meshes flawlessly with other components and eliminates a lot of importing and exporting hassles not to mention inconsistencies. Well worth the money of you like playing in Poser and value your time.
